Progress against  #37.

* views folder has been renamed to templates
* Templates have been renamed from custom-* to mm-angular-strap-* to better represent what they are
* home.js and home.html have been moved out of templates to the root directory of the demo
* All directives have been split into separate files in the directives folder
* A basic gulp build is now in place that will concatenate and minify the directives into a single file called mm-angular-strap-directives.js
* The customizedApp.js file has been reduced to just the app.config used by the demo (though some of that will need to be genericized so it can be used in production apps)
